Two liquids X and Y on mixing gives a warm solution. The solution is ______.
Assertion: An ideal solution obeys Raoults Law.
Reason: In an ideal solution, solvent – solvent as well as solute – solute interactions are similar to solute-solvent interactions.
Which solution has the lower freezing point? 10 g of methanol (CH3OH) in 100g g of water (or) 20 g of ethanol (C2H5OH) in 200 g of water.
The observed depression in the freezing point of water for a particular solution is 0.093°C calculate the concentration of the solution in molality. Given that molal depression constant for water is 1.86 K Kg mol-1.
For ideal solution the volume of mixing of the pure components to form the solution is ____________.
The rate at which a solid dissolves in liquid does not depend on ____________.
Which relationship is not correct?
If two liquids A and B form minimum boiling azeotrope at some specific composition then ______.
Why soda water bottle kept at room temperature fizzes on opening?
What is “semi permeable membrane”?
Assertion: When a solution is separated from the pure solvent by a semipermeable membrane, the solvent molecules pass through it from pure solvent side to the solution side.
Reason: Diffusion of solvent occurs from a region of high concentration solution to a region of low concentration solution.
The pH of a solution of hydrochloric acid is 1.5. Calculate the concentration of the acid.
Which of the following gave the idea of a nucleus of the atom?

Assertion (A): The enthalpy of mixing Δmix H is equal to zero for an ideal solution.
Reason (R): For an ideal solution the interaction between solute and solvent molecules is stronger than the interactions between solute-solute or solvent-solvent molecules.
